  • The Importance Of Digital Signal Processing

    ABSTRACT: Multiplications and Accumulations find tremendous applications in the domain of Digital Signal Processing (DSP). On contrast to this, currently there is an immense requirement of hardware dedicated to serve the purpose of speed enhancement. Reversible circuits are being deployed on a large scale to design the Multiply Accumulate units with the advent of quantum computing. In this paper, we present a real time development model of a 4 x 4 Multiply Accumulate unit by exploiting reversible logic for optimizing energy consumption. KEYWORDS: Multiplications and Accumulations, DSP, Reversible Logic, Reversible Gates, Power Dissipation, Reversible Multiplier. I. INTRODUCTION One of the most crucial issues of concern in current technology…

  • Disadvantages Of Speech Reverberation

    However, the learning-based algorithms are generally resource intensive and require a long time context, which makes them hard to implement in real time processing. In [16], Nakatani et al. proposed harmonicity-based dereverberation (HERB) methods, which modeled RIR inverse filters as a ratio of the direct path component to the received signal. The design of the inverse filters exploited the harmonicity characteristics of the speech signal and estimated the filter coefficients in two distinct…

  • Fiber Optic Sensor Essay

    detection of pollutants in soil, water, air with biological sensors which has attracted interest as these facts are directly related to human health. Plus these sensors averted the need of setting up a lab and gathering samples for investigation which is expensive, time consuming and invasive. High sensitivity, minimum weight and large bandwidth makes fiber optic sensors the optimum photonic devise in radiative environment like nuclear power plants, where there is a need of evaluation and…

  • Essay On Advantages And Disadvantages Of OFDM

    2 OFDM SYSTEM:- OFDM system is divided into three parts 1. multi carrier modulation 2. frequency division multiplexing 3. Orthogonal frequency division multiplexing. 1.Frequency division multiplexing:- Frequency Division Multiplexing is a form of signal multiplexing which involves assigning non – overlapping frequency ranges or channels to different signals or to each user of a medium. A gap is left between each of these channels to ensure that the signal of one channel does not overlap with…

  • Nt1330 Unit 5 Case Study

    Each totaltraffic graph in the method section shows the server or the client with the above RTT and Window Size as incoming and outgoing traffic. The horizontal axis represents the time in seconds and the vertical axis represents the measured traffic in bytes. The graphs presents the increase of traffic once the experiments starts and ends. Case 3. In comparing the window size and RTT staying the same, the traffic decrease once the window size increase. In comparing RTT and the window size…

  • Oscilloscope Response Paper

    The experimenters followed their experimentation with analysis of the data obtained. The experimenters first contemplated the applicability of the Probe Comp test signal to biological systems. The experimenters reasoned that the test signal was not an effective description of a biological system because the test signal did not exhibit the noise present in biological systems. While considering the observations of the oscilloscope and biological systems, the experimenters considered which settings…

  • Filter Design And Harmonic Analysis In Power System

    standards to protect the sensitive loads, it is necessary to enclosed some form of filtering device to the power system. Harmonics are also increases overall reactive power demanded by equivalent load. Designing of filter is one of the methods to control harmonic alleviation problems and improve power quality by delivering electrical power to the system. This paper presents the evaluation of filter design and harmonic analysis to the system network. Goal of this paper is extraction of…

  • Pipelined Adc Architecture Analysis

    The another advantage of this ADC is it is less complex because the DAC circuit is not used in the ADC architecture. The main drawback of this ADC is that it is only suitable for low bandwidth input signals. 4.2 Summary of ADC Architectures All the most popular ADC architectures have been explained in detail in previous sections. The flash ADC architecture is the fastest, the SAR ADC gives low power applications, the ∑∆ ADC is useful for high resolution applications. All the ADCs have…
